"It is a wellknown fact that the eflici of an engine is contingent, among other thin s,"upon the maintenance oftheoll at ficientl low temperature to "avoid boiling and a equatelyeool the engine. Attempts in the past in this direction havebeen IIlOIei or less successful, but in every 'ca'se, so far as I am aware, such attempts have" been accomplex ant /or expensive.

Instead of having a directi connection .by

means of conduits from the bottom of the drip or mud pan indicated generally at 1,.

having side flanges, the flange 2 being free,

V leakage-of fluid between the channel memand disposed adjacent the. engineA, and the other flange3 being secured to the chassis or frame E, the bottom 4; of the 'pannormally lying. ina horizontal ora somewhat inclined plane. By my inventionI made use of the mud pan 1 so. that the latter, in addition to its natural function, also forms a wall of a cooling conduit forthecooling water; To this end'I provideaf shallow channel-shaped: member indicated gjenerallyat 5, having its bottom or web extending substantiallysparallel with the bottom of the mud pan. 1, said webincluding a plurality of downwardly ex tending heat dissipating fins 6', having spaced walls}, the spaces thus formed being injcommunication.with-the interior of the channelmember-5. The flanges 8 of. the member 5 extend upwardly and are provided with-lips 9 securedito theedgesof the bottom of .themud pan 1 by weldinguor any other :suitab1e.means, to thereby prevent ber 5 and the mud pan 1. It will be. apparent that the elongated pockets 701 between the walls 7 of the fins 6 provide for a very appreciable increase in surface contact between thefluidand the walls'of the conduit formed by the parts 1 and 5,'so that the heat dissipating action of the fins 6 is greatly enhanced. 1 L

i It; will be appreciated that withoutin any way reorganizing the engine and its appurtenant: parts, a duplicate construction of theopposite side'of the engine and the opposite side of the frame or chassis E as shown :in Figures and "3, in order to provide for coolingofany other fluid, such as oil.-. Each conduitformedby the parts I and .5 is preferably closed at its'ends and connected with the remainder of th'e'fluid system, of [which .it' forms. a. part, bysuitable piping. -"To: avoid confusion, the conduit formed ln-accordance with my invention and appearing at the right in Figure? is indi- "catedat 10 whilethat 'at' the left is indicated at ,11'. -Referring to the conduit indicated atlQ, .wh'oseends are closed at 12 by welding :or. other suitable means; it will be re enters the crank case. r

noted that conduit 13, connected to the same 7 p at 14,communicates with the waterpump (3' at l5,'the pump C'being in turn connected in the conventional way to the water jacket F, and *the. latter communicating with .the

.radiatorB. A tube. or-the like 16 connects the lower part of the radiator with the cooling conduit 10 as shown at 17.

It will be'ap'preciated from the foregoing that, starting with thepump C, the water moves ina cycle from the pump to the jacket E, whence it flowsto the top ofthe radiator B, leaving the same at itsibottom through the coupling or tubing lofand entering the] conduit. 10 and substantially filling the same, leaving the same at .14 through the medium of the coupling'eleinent 13 to enter the pump C, thereby completingfthe cycle of flow.

.As stated heretofore, bothcontainers' 10 7 and '11 may be connected to the water cirv culating system, or bothjmay be connected to the oil or other fluid circulating system,

or each may be connected to a different sys- -,ten 1. (For the purpose of this description,

however, I employ the: second container or conduit 11 in-connection with'fan oil circulatory system. To this end, I connect. piping or the like 18 at oneend 19. to the V i conduit 11 and theother end 20 to the crank-L case, preferably adjacent the 'other'end of the oil pan 21. Other, piping onthe like 22 Y isconnected at 23 to, another portion of the conduit 11-, the oppositeendQl of. the piping extending well within the .oil pan'21 to cooperate with the oil pumpD shown in d otted lines in Figure 3. Of course, a suitable; fluid tight connection is made between the piping 22*and thecrankcase. 'Oil pumped I by'the'pump'D enters the tubing 22, substantially fills the container 11, and: leaves thelatterby way of the tubinglS'and then It will be evident thatby emp1oying, fins,-, I am enabled to provide for maximum radiation for a given, cubical content of the .container'z'fl IVhile- I have describedv my invention as 7 providing fins extending downwardly from the-trough-like member -5,.-it will.be=appreciated that, if desired, the'fins could be .made' to extend upwardlyv instead, and also that the drip. or mud pan 1 could beilikewise formed; Moreover, the fins are preferably,

though not necessarily, spaced apart a dis tance equal to their owndepth.

. It is to be understood that while the in vention is illustrated as having the two connections providing the entry'to and exit from each container in proximity toeach other, these connections,if desired, may be located at opposite ends of I the container or in any other vrelation; I

, N owl desire it understood that although 7 I have illustrated and described. in detail the preferred embodiment" ofmy invention,

the invention is not to be thus limited but. only insofar as defined by the .scope'and nal hollow heat dissipating fins, thereby' providing increased contact area with the water, the top wall of the conduit constituting a drip pan for receiving oil and other foreign matter escaping from the upper part of the engine.
